Title: Light-sensitive modified epoxy resins
Inventor: LARIDON URBAIN LEOPOLD
IPC: C08G65/28
Filed: 1965-06-01
Abstract: Light-sensitive compositions comprise soluble modified epoxy resins obtained by reacting a chlorosulphonyl or chlorocarbonyl substituted azidoaryl compound with a polycondensate of a bisphenol with epichlorohydrin.  The modification is performed in the presence of pyridine and, optionally, of methylene dichloride as a solvent. After dilution of the reaction mixture with methylene dichloride the product is recovered by precipitation with methanol.  The compositions preferably contain organic solvents and photosensitizers.  The compositions are photochemically cross-linked on exposure to actinic light.ALSO:p-Azidobenzoic acid is prepared by adding aqueous NaNO2 and NaN3 successively to a cold solution of p-aminobenzoic acid in strong hydrochloric acid and filtering off the precipitate  p-Azidobenzoyl chloride is obtained by reacting the acid with SO2Cl2.  Sodium p-azidobenzenesulphonate is prepared by dissolving sulphanilic acid in aqueous Na2CO3, cooling, and adding successively aqueous NaNO2, aqueous HCl and aqueous NaN3.  The product is precipitated by the addition of NaCl. p-Azidobenzenesulphonyl chloride is obtained from the sodium salt by reaction with SO2Cl2.

Title: Data processing apparatus
IPC: G11C29/48
Filed: 1972-05-25
Abstract: 1340283 Memory error detection INTERNATIONAL BUSINESS MACHINES CORP 25 May 1972 [11 June 1971] 24560/72 Heading G4C A data processing system includes a monolithic semi-conductor data store and a correction system arranged to interrogate the memory systematically when the memory is not otherwise being used and to record erroneously stored data and its corresponding memory address. The arrangement is utilized with monolithic data stores since these tend to acquire errors, e.g. due to noise &c., as a function of time. In the system shown memory 10 is shared by a central processor 22, an input/output device 20, and the correcting system 40 by means of a conventional priority circuit 38 which gives precedence to the I/O unit and the CPU over the correction system 40 unless a particularly serious error is detected requiring an interrupt. Data in memory 10 is addressed via gate 36 which selects the addressing source in accordance with signals from priority unit 38 and decoder 32 and is read out to parity corrector 14 which as described is a conventional single bit correcting Hamming circuit utilizing Exclusive- OR gates. The data, having been corrected if necessary, is then fed to output buffer 16 for routing over output bus 18 to the appropriate unit. If an error is corrected a signal is supplied to correction circuits 40 which include a store in which the uncorrected erroneous data and its memory address are stored. A signal is also supplied to gate 24 to enable the corrected data to be written into the memory. The correction circuits may also include a programmed computer which may perform diagnostic functions, e.g. arranging the system to avoid consistently faulty memory locations by counting each time a particular memory address fails. Circuit 40 is also responsible for systematically interrogating the memory 10 to search for and correct erroneous data. An AND gate receives signals from the parity corrector indicating that a correction is not in progress and from priority circuit 38 indicating that the memory is not being used. The output of the AND gate stops a counter which is arranged to cycle through the memory addresses. Address gate 36 is also controlled to gate the counter contents to the address decoder in order to address the memory. The operation is then similar to ordinary operation with errors being corrected, rewritten, and recorded (see above).
